OR Gate
Practical case: Nurse call bell
Level: Basic – Implement an OR gate to activate an alert from two independent switches.
Practical case: Multi-perimeter intrusion detection
Master Digital Electronics by building a 4-zone security alarm. Use an OR gate to trigger a relay and siren instantly when any single access point is breached.
Practical case: Simple electronic voting system
Master Digital Electronics by building a voting system with an OR gate. Design a circuit that triggers a visual signal when any judge activates a switch.
Practical case: Production Line Fault Monitoring
Master Digital Electronics by building a safety circuit with an OR gate. Stop a conveyor belt instantly when temperature or jam sensors detect faults.
Practical case: Redundant motor starter system
Master Digital Electronics by building a dual-start motor control circuit. Use an OR gate to trigger a relay and drive heavy loads from two distinct locations.
